What would you like what type of reactions is 4 Ag plus O2 arrow 2 Ag2O?

Answer 1

2HgO --> 2Hg + O2 is a decomposition reaction, in which Mercury oxide is decomposed into the element Mercury and oxygen gas. A decomposition reaction is one in which a more complex substance is broken down into its simpler components.

Answer 2

It’s a Decomposition

Answer 3

Ag in Ag2O has oxidation state = +1

Ag in Ag(s) has oxidation state = 0

O in Ag2O has oxidation state = -2

O in O2 has oxidation state = 0

Ag is "reduced" from +1 to 0 and is therefore the "oxidizing agent"

O is "oxidized" from -2 to 0 and is therefore the "reducing agent"

so this is an "oxidation-reduction" reaction. aka redox.

at the same time, it is also a decomposition reaction. a decomposition reaction goes like this.. AB ---> A + B

it isn't a synthesis reaction, that would look like A+B ---> AB

Nor is it a combustion reaction. That would be A + O2 ---> AxO2

so the correct answer is (e). two of these. (a) and (c)

Answer 4

2HgO --> 2Hg + O2 is a decomposition reaction, in which mercury oxide is decomposed into the element mercury and oxygen gas. A decomposition reaction is one in which a more complex substance is broken down into its simpler components.

Answer 5

Oxidation:

Balanced equation written as:

4Ag + O2 --> 2Ag2O

Answer 6

Its reaction is decomposition because it is complex to two simple elements

Answer 7

I9

Answer 8

Decomposition
